Product Description:

The 131B1932 AC drive is produced by Danfoss for the VLT FC 301 Automation Drives series. It converts fixed-frequency three-phase input into a variable output that lets control systems regulate the speed of asynchronous motors used in pumps, blowers, and general material-handling equipment. By delivering closed-loop torque control, the unit allows tighter process regulation, energy savings, and smoother starts than across-the-line operation, making it a common component in automated plants and commercial HVAC installations.

The drive supplies a continuous motor current of 13 A when fed from 380–440 V lines, enabling accurate control of loads up to 5.5 kW. Its output is configured for a three-phase motor, and the inverter can tolerate an overload of 160 % for one minute to handle acceleration or momentary process peaks. Input terminals accept mains voltages up to 480 VAC. The graphical LCP control panel provides parameter access and trend viewing directly from the cabinet door. Because no brake chopper is integrated, excess regenerative energy must be diverted through external hardware if frequent deceleration cycles are expected. Frame size A5 supports installation in compact panels and accommodates the series' modular accessories.

To withstand dusty or damp production areas, the housing carries an ingress protection rating of IP55 and meets NEMA Type 12 requirements for oil-tight enclosures. Internal power dissipation is limited to 187 W at full load, so installation airflow must remove the generated heat while accounting for the A2 electromagnetic compatibility class for conducted emissions. The aluminum chassis stands 420 mm high, spans 242 mm in width, and measures 200 mm deep, allowing side-by-side mounting with other A-frame inverters. These dimensions provide space for cable entry while keeping the drive suitable for control panels with limited depth.
